Title
(EN) AUTOMATED SCHEDULE CALCULATION FOR CONTROLLING A CONSTELLATION OF SATELLITES
(FR) CALCUL DE PROGRAMME AUTOMATISÉ POUR COMMANDE D'UNE CONSTELLATION DE SATELLITES
Abstract
(EN)
Particular embodiments also include a optimization and simulation service that can analyze different variables for scheduling the satellites. The optimization and simulation service operates automatically to schedule satellites and ground stations to obtain their highest attainable performance relative to the system operator's goals as well as to respond to various unexpected behavior or events and performance variations, modifying the schedule accordingly. The optimization and simulation service leverages the sparsity of the system in the optimization such that the optimization and simulation service can calculate the change in utility for one satellite without reference to unimpacted satellite schedules. This allows the schedule to be calculated efficiently and provides optimum usage of the satellites.
(FR)
Des modes de réalisation particuliers comprennent un service d'optimisation et de simulation qui peut analyser différentes variables pour programmer les satellites. Le service d'optimisation et de simulation fonctionne automatiquement pour programmer des satellites et des stations terrestres afin d'obtenir leurs performances pouvant être atteintes les plus élevées par rapport aux objectifs de l'opérateur du système ainsi que de répondre à divers comportements ou événements et variations de performances inattendus, modifiant le programme en conséquence. Le service d'optimisation et de simulation influence la rareté du système lors de l'optimisation de telle sorte que le service d'optimisation et de simulation peut calculer le changement d'utilité pour un satellite sans référence à des programmes de satellites non touchés. Ceci permet de calculer efficacement le programme et fournit une utilisation optimale des satellites.
